Abstract
We present the first integrated multimode photonic spectrograph, a device we call PIMMS #1. The device comprises a set of multimode fibres that convert to single-mode propagation using a matching set of photonic lanterns. These feed to a stack of cyclic array waveguides (AWGs) that illuminate a common detector. Such a device greatly reduces the size of an astronomical instrument at a fixed spectroscopic resolution. Remarkably, the PIMMS concept is largely independent of the telescope diameter, input focal ratio and entrance aperture - i.e. one size fits all! The instrument architecture can also exploit recent advances in astrophotonics (e.g. OH suppression fibres). We present a movie of the instrument's operation and discuss the advantages and disadvantages of this approach.
